Abstract (en)

[origin: WO2016198515A1] A drinking straw having an internal coating for delivery of an active agent when the straw is used to consume a beverage is provided. The active agent includes sweetener, flavour, a nutrient and/or a pharmaceutical and optionally colour. The coating is prepared by mixing a modified cellulose with water to form a paste or gel. The coating is then used to coat the inside surface of a drinking straw to a thickness of up to 1 mm. The coating is dried to reduce the water content to less than 5% by weight. Liquid drawn through the straw breaks down the modified cellulose releasing the active agent into the liquid, for consumption.
